The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -1
We get the answer: x = -19
-42-x = -23
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -1
x = 19 / (-1)
We get the answer: x = -19
